Abstract

L'invention concerne un procédé pour produire de l'acide chlorique, consistant à introduire une solution de chlorate de métal et un acide dans des compartiments séparés d'une cellule d'électrodialyse, à extraire les protons de l'acide et les ions chlorate du chlorate de métal pour former de l'acide chlorique dans un compartiment de ladite cellule d'électrodialyse, et à extraire les ions métal du chlorate de métal pour former une solution d'un sel métallique dans un autre compartiment de ladite cellule d'électrodialyse. L'invention concerne également un dispositif permettant la mise en oeuvre du procédé, ainsi qu'une méthode de production de dioxyde de chlore.
